All about Neem Oil

All about Neem Oil

What is Neem Oil?

Neem oil is pressed from the seeds of the Azadirachta indica tree, a fast-growing evergreen native to parts of Asia. Neem oil contains over 150 biologically active compounds, known as limonoids. Some highly active limonoids found in neem oil include azadirachtin, salannin, meliantriol, nimbin, nimbidin, nimbinin, & nimbolides. These active compounds allow neem oil to function with multiple modes of action, including as an antifeedant, insect growth regulator, insect repellent, molting disruptor, and fungal growth inhibitor.

Terramera, the manufacturer of RANGO, uses proprietary testing to ensure the presence of key limonoids in every container of RANGO. This results in a premium, consistently effective, broad-spectrum fungicide, insecticide and miticide. 

Neem oil extraction

Neem oil is extracted from Azadirachta indica seeds, which have the highest concentration of insecticidal and fungicidal compounds in the plant. There are three common methods of neem oil extraction - solvent extraction, heat extraction, and cold-pressing.

Solvent and heat extraction separate the compounds based on their solubility. These processes may compromise the integrity of limonoids, resulting in potential variability in the final product. In the solvent extraction process, Azadiracthin is separated for use in the production of materials such as Azaguard, Neemix and Azera. The remaining oil is referred to as "Clarified Hydrophobic Extract of Neem Oil" and is used in products like Trilogy.

Cold pressing is a mechanical process in which neem seed kernels are crushed and squeezed. Since there is no heat generated and there are no solvents used in this extraction, the resulting oil contains the complete limonoid profile, including Azadirachtin. RANGO is made with cold-pressed neem oil.  

Premium emulsion, Superior suspension

Because neem oil is a naturally-derived material, creating a consistently stable and usable product requires attention to detail and precision formulation.  Rango is designed to handle and go into suspension easily, ensuring that tank mixing and spray applications are trouble free. 

When mixed according to label directions, Rango quickly forms a stable emulsion and can remain in suspension for up to 48 hours. A well suspended tank mix results in thorough and even coverage when sprayed, thereby providing maximum effectiveness.

RANGO - All You Need in One Jug

Neem oils are true multi-use materials and can prevent or control a wide range of insects, diseases and mites in many crops. 

Neem oils function as excellent insect repellants and also control targeted pests on contact or through ingestion. RANGO has proven to be successful in managing pests such as thrips, caterpillars, aphids, plant bugs and mites across all life stages. For more field data : Product Brochure

As a cold-pressed neem oil containing a full limonoid profile, RANGO is also a powerful fungicide for use in the prevention of powdery and downy mildews, as well as botrytis. There are no known resistances to neem oil, making it a valuable part of integrated pest management plans for both organic and conventional farms.

Best Practices

For the best results, apply RANGO as a preventative treatment for diseases of concern and as a repellent prior to the arrival of anticipated insect or mite pressure.  If a pest outbreak does occur, treat as early as possible.  Re-treatment intervals range from 5-21 days, depending on the target pest or disease, whether its presence is established, the severity of the outbreak and environmental conditions.
